This article traces the genealogies of the legal concept ‘spreader of corruption’. Although some scholars working on Ottoman law consider this concept to be part of the Ottoman ḳānūn tradition, the history of its adaptation by Ottoman jurists actually dates back to the Qarakhanid period (eleventh century CE). It acquired its legal meaning as a result of jurisprudential debates among Ḥanafī jurists in the context of political turmoil and violent factionalism among madhhab s. Later, Seljuq and Golden Horde legal-textual traditions served as conduit for Ottoman jurists to adapt the concept in order to apply it to a variety of criminal acts. This article explores how the ‘spreader of corruption’ concept was reinterpreted over the centuries and how it contributed to the enforcement of law in the Ottoman context.
